TUBULAR LANTERN.

SPECIFICATION forming part of Letters Patent No. 375,020, dated December 20, 1887.

Application filed December 4, 1886. Serial No. 220,740. (No model.)

To all whom it may concern:

Be it known that 1, JOHN HENRY STONE, of the city of Hamilton, in the county of \Veutworth, in the Province of Ontario, Dominion of Canada, have invented certain new and useful Improvements in Tubular Lanterns, called or known as the Pcrfect-Lift Lantern, and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same.

The invention relates to tubular lanterns; and it consists in the novel features of construction and new combinations of parts hereinafter fully described, and definitely pointed out in the claims.

By reference to the drawings forming part of this specification it will be seen that Figure 1 represents a side elevation of a tubular lantern. Fig. 2 is a similar elevation showing one tube only. Fig. 3 is a cross-section of the upper central tube, showing grooves. Fig. 4 is a crosssection of the upper central tube and guide-wires on the line at m, Fig. 1.

A A are the side air-tubes.

B is the perforated disk, resting on the burner-cone G.

D is the guard attached to the perforated disk B, and made to spring up on each side of the globe E. A reflector may be made to slide on the said guard.

G is a wire globe-holder fastened to the deflector-plate H, and in passing downward is bent outward to conform to the shape of the head of the globe, and then bent horizontally and clasps the globe about threefourths of its circumference under the bead, the-ends of the wires terminating in a round bend backward, as, shown.

I is a small projection on the inside of the vertical portion of the globe-holder and made to rest on the top edge of the globe E, to assist in keeping it in its place.

J is a spring locking-bar, its lower end secured to the front guard, D, and bent at a to conform to the globe's bead, and its extreme upper end bent over the edge of the deflectorplate H. This device with the globe-holder G secures the globe in position.

K is the central air-tube, to which are secured the tubes A A, and it is formed with a groove, 1), on each side, as shown at Fig. 3. The said tube K is formed slightly tapering from the top to the bottom.

L is a brass band or collar placed around the vertical tube K and fastened to or stamped in the deflector H, which is also made of brass, the two formed to slide up and down smoothly on the tube K without cutting it. y

c is a double guide-wire secured to the band L and let into the grooves 11 on each side of the tube K and bent at the top a short distance above the top of the tubes A, forming a thumb-ring to raise the globe. It will be observed that the reason why the tube K is slightly larger at the top than the bottom is in order to bind the band L on the upper part of the said tube when the globe is raised to its highest elevation and hold the globe up as long as desired.

M is the handle for carrying the lantern.

It will be observed that the globe can be raised by five different ways-via, by means of the thumb under the disk, by the guardwire D, by the globe, by the deflector, by the guide-wire c. To release the globe all that is necessary is to draw the globe forward out of the opening inthe spring globehold-or. On returning the globe to its place all that is necessary to do is to put the locking-bar J over the bead of the deflector.

Having thus described my device and its advantages, what I claim as my invention, and desire to secure by Letters Patent, is

1. The combination, in a tubular lantern, of the central tube, K, and deflector H, sliding thereon, the perforated disk 13, the globe E, the guard D, attached to said disk, and the spring locking-bar J, secured to the guard D,and adapted to engage with the deflector H, substantially as described.

2. The combination, in a tubular lantern, of the central tube, K, and deflector H, sliding thereon, the perforated disk B, the globe E, the guard D, attached to said disk, the spring locking-bar J, secured to the guard D, and the globe-holder G, secured to the deflector H, substantially as described.

3. The combination, in a tubular lantern, of the globe E, the perforated disk B, guard D, secured to said disk, the'spring lockingbar J, globe-holder G, the central tube, K,

5 provided with grooves, the deflector H, having collar L, and the guide-wires a, secured to the said collar and fitting in the grooves 12 b, substantially as described.

Dated at Hamilton, Ontario, this 24th day of July, A. D. 1886.

JOHN H. STONE.

In presence of- FRED. BARTLE, WM. BRUCE.
